PCB Mount 5.5 x 2.1mm DC Barrel Jack

Description

A “PCB Mount 5.5 x 2.1mm DC Barrel Jack” is a common type of power connector used in electronic circuits and devices. This specific type of DC barrel jack is designed for easy installation on a printed circuit board (PCB). Here’s a description of its key features and characteristics:

1. Connector Type: This is a DC (Direct Current) barrel jack, which is used for connecting an external power source, typically a DC power supply or battery, to a device or PCB.

2. Size: The connector has a 5.5mm outer diameter and a 2.1mm inner diameter, which is a standard size for DC barrel jacks. The 5.5 x 2.1mm dimension is a common specification used for various electronic devices.

3. PCB Mount: This type of DC barrel jack is designed for mounting directly on a printed circuit board (PCB). It has pins or leads that are soldered onto the PCB for a secure electrical connection.

4. Power Input: It is used as a power input connector, allowing a device to be powered by an external DC power source.

5. Polarity: DC barrel jacks have a center pin (usually positive) and an outer ring (usually negative) to ensure correct polarity when connecting the power source.

6. Versatility: These connectors are commonly used in a wide range of electronic devices, including power supplies, routers, modems, audio equipment, and various consumer electronics.

7. Ease of Installation: The PCB mount design makes it convenient for manufacturers to integrate the connector into their products during the assembly process.

8. Secure Connection: Soldering the leads of the DC barrel jack to the PCB ensures a stable and reliable electrical connection.

9. Compatibility: The 5.5 x 2.1mm size is widely used, so it’s compatible with a variety of power supplies and devices that use the same connector size.

10. Center Pin: The center pin is typically used for the positive voltage, while the outer ring is connected to the ground (negative) of the power source.

A “PCB Mount 5.5 x 2.1mm DC Barrel Jack” is a practical choice for applications where a reliable and standardized power input connection is required on a printed circuit board. It is commonly used in various electronic devices and can be easily integrated during the manufacturing process, providing a convenient way to power or charge devices.
